摘要
【目的】评价我国猪肉进口的环境效应,提出相应的建议对策。【方法】从规模效应、结构效应、技术效应3个角度,引入猪肉行业相关变量修正EKC模型,验证并分析猪肉进口贸易的环境效应。【结果】估算了我国生猪生产污染物排放中化学需氧量COD、生化需氧量BOD以及氮排放量TN。结果显示我国猪肉进口环境库兹涅茨曲线存在。从规模效应、结构效应、技术效应3个角度分析猪肉进口贸易的环境效应。【结论】我国应发展生态猪业,控制生猪养殖规模,适度扩大猪肉进口,积极调整猪肉业结构,引进外国先进猪肉生产技术,提高猪肉产业可持续发展能力。
Objective]To evaluate the environmental effects of China pork imports and put for-ward corresponding suggestions.[Method]Introduce the pork industry related variables into the modified EKC model from three perspectives as scale effect,structure effect and technical effect.[Results]The Chemical oxygen demand （COD）,biochemical oxygen demand （BOD）and nitrogen emissions （TN）were estimated in the pollutant emissions of pig production in China.And the en-vironmental Kuznets curve relationship model （EKC）was proved to exist in China pork imports.[Conclusion]The following suggestions were put forward：ecological pig raising with moderate scale,moderate expansion of pork imports,active adjustment of the pork industry structure,in-troduction of foreign advanced technology,improvement in the ability of sustainable development in pig industry.
